There's a page here that explains the TrayApp problem and how to solve it quite well.

As a first port of call, press CTRL-ALT-DEL to bring up Task Manager. Click the processes tab and see if there's any processes in the list periodically using an unusually high percentage of processor time (third column along) If you don't see anything there, that doesn't mean there's no processes behaving this way. The process responsible could be hidden by spyware.

If you set-up your Outlook Express (Tools>Accounts>Mail Tab) gmail POP settings to those advised in the Google Mail Configuration Instructions then incoming domain mail (forwarded to Google Mail) will be available on Outlook Express via POP Download. You may have enabled Forwarding also on Gmail's settings page inadvertantly. I set it up by disabling forwarding and enabling POP Download. If after following their instructions you still get no joy from incoming domain mail contact your webserver staff. Another thing may have happened: if you'd set up 2 email addresses to incorrectly forward to each other, then a loop situation could occur. One of the mail servers will recognise the loop, stop responding and then block it automatically.

You've tried to reinstall XP using a repair install. If you've already tried that and it hangs then the only way to get XP working here is a clean install. To avoid losing documents you need a bootable disc with utilities to recover and copy the irreplaceable files elsewhere BEFORE you do a clean install. Another way would be to swap your primary hard drive and the second hard drive you used for Linux round and do a clean XP install on the new primary drive. You can then run salvage operations on irreplaceable files using the new XP installation to read the old one. Once you've backed up the files, you can swap your drives back again then reinstall XP cleanly on your original primary drive. These operations would be a whole lot easier with utilities like Norton Ghost or Acronis True Image but you need to buy them ;)

Recovery console asks for a password even if there isn't one. Just hit enter.

What type of video files are you trying to play? You did mention you now had a clean system with just XP and drivers installed but did you reinstall any codec packs? Seems odd that sound and video worked fine after your initial reinstall up to when you installed codecs. If you need codecs, try the Gordian Knot codec pack on doom9.org. Don't download codec packs from limewire (I personally wouldn't download anything from limewire period)

Try running the System Restore utility to restore your PC to an earlier time. Press Start > All Programs > Accessories > System Tools > System Restore. Then choose a date from the calendar to restore to and let System Restore do its thing. If that works it will avoid having to reinstall the operating system. You won't lose any documents this way either. Good luck!

There's a whole list of possible problems. One simple problem could be the mouse and keyboard are plugged in the wrong way round. Do you have printers and other peripherals connected to the computer? If so, try unplugging one by one and see if that solves it. Other than that, could be the graphics card has failed, could be the motherboard failed, memory may be faulty. Could be a memory chip needs reseating. Maybe the power supply is failing. Maybe the CPU fan has stopped working. Are you getting any series of beeps from the PC? After ruling out simple things, unless you have access to spares it's going to be difficult to establish the source of the problem without the help of a repair shop.

No information on Packard Bell's website about an iXtreme 850. There's an 8500 model but not sure if that's your one. If you go on to Packard Bell's website under support, you can enter the serial number on the back of the machine and this will show you specific information regarding the model of your PC. In most cases the motherboard should auto detect the AGP card and you'll get basic VGA output on the monitor until you've loaded up the drivers for it. Can't be sure until you give more information on the model of your PC though.

If your machine still doesn't come to life after a PSU replacement, then it's probably taken out the mainboard also. Emachines are notorious for this problem. So much so it prompted one of our suppliers to jokingly ask "Are these socket 478 boards for Emachines repairs by chance?"

Are you using a wireless router/modem?

Search in Google for Autoruns by Mark Russinovic, it's on Mircosoft's website. Download, unzip and run. There's tons of loading points that aren't covered by msconfig. Click on File > Find and enter KODAK. Then delete the offending item.

Unlock file link on this page: http://www.the-scream.co.uk/forums/t24186.html?&highlight=voyager+2500v Remember when you've found the link on that page, right-click and select "Save Target As" in Internet Explorer or "Save Link As" in Firefox to download the file. The instructions are at the bottom of the page (they're also on BT's site btw)

Rule out the phone itself by trying another phone.

Initially try resetting your broadband router. Switch off the power to the router, wait a while and switch it back on. If you're running Norton Internet Security or similar, temporarily disable it to check whether a firewall is blocking it. If that doesn't fix it, scan the machine for spyware or virus infection. There are other reasons but let's try that to begin with.
